It was one year ago a white supremacist opened fire at Sikh Temple of Wisconsin, killing six people, including the temple's president.One of those who survived the shooting was Sikh priest Punjab Singh, 65. He remains in a care facility after being shot in the head."You cannot explain the emotions. And my father, he just not a father for me, he is my best friend," said Punjab Singh's son, Raghuvinder Singh.Raghuvinder Singh flew to Milwaukee from India immediately after the shooting to see his father, who was only in Oak Creek four days as a guest preacher.Punjab remains too fragile to be moved back home to India, and his recovery is measured."They're trying their best, but after his gunshot, he cannot speak. He cannot move any part of his body. He can only answer us with yes by double blinking his eyes," Raghuvinder Singh said.Raghuvinder, his brother and mother are all in the Milwaukee area now indefinitely from India. They take shifts keeping a round-the-clock vigil at Punjab's bedside."I will always ask for prayers. I know that it works, and it is working," Raghuvinder Singh said.Punjab Singh is a world-renowned preacher for the Sikh faith.The two sons have not seen their wives or children in India in the past year, and they've been unable to get visas to visit here.
